4 Claims. (Cl. 292-76) This invention relates to a metal window construction of the type that includes a metallic window frame having vertical sash member receiving channels in the jambs thereof, in which channels a sash member, including vertical side rails and horizontal top and bottom rails, is slidably mounted, and in which window construction spring counter balancing devices for the sash member are mounted in the channels of the frame between the side edges of said sash member and said jambs. s

The invention is particularly -directed to a spring equalizer which cooperates with the spring balancers to permit the sash to be easily raised and lowered and to be maintained in its various positions.

It is an object of the invention to provide a spring equalizer which will be carried by the sashv and will bear against and slide freely on a surface of the window frame to exert a pressure thereon which will restrain the movements ofthe sash under the influence of the balancer springs and embodied in which is an adjustment device for varying the degree of pressure exerted by the equalizer against said frame, which adjustment device is so located that it is accessible for adjustment when the window sash is operatively located in the window frame and while the sash is being raised and lowered.

In the drawings:

Figure 6 is a vertical sectional view showing the spring equalizer adjustment;

Figure 7 is a plan view of the spring equalizer and its associated parts; and

Figure 8 is an elevational view showing the spring equalizer as applied to the lower portion of a sash.

Referring to Figure l, the window construction, the sashes of which are of the double hung type,

2 comprises a frame 20, av lower sash 2|, and a muntined upper sash 22. As disclosed in Figures 2, 3 and 4, the window frame includes a head 23, a sill 24 and jambs 25.

Each of these frame and sash elements may be formed 0f an extruded aluminum section.

The sill 24 includes anges 26 and 27, which extend downwardly from the top 28 of the sill to form a horizontal recess for the reception of the caulking 29, whereby the frame may be sealed with respect to the masonry sill 30 of the building structure.

The sill 2d also includes a ledge 3l, against which the lower rail of the lower sash abuts when the latter is in its ultimate lower position. The head 23 includes an inwardly extending shoulder 32, from which an upwardly extending flange 33 projects. A second and shorter flange 34 cooperates with the flange 33 and the shoulder 32 to form a recess for the reception of the caulking 35.

The inner longitudinal side of the head 23 is provided with an extension 36 for the reception of.

the wood trim 31.

Each jainb 25 includes channels 38 and 39 (see Figure 3) adapted, respectively,` slidably toreceive the upper and lower sashs and to receive the spring balancers and spring equalizers.

Each jainb 25 is also provided with inwardly directed anges 40 and M for attachment to an anchor d6. It also includes an extension 42, which is adapted to cooperate with the trim 63. A caulking flange si is provided, against which the caulking d5 may be placed. Y

The head 23, the sill 2t and the opposite jambs 25 are secured together at their adjacent ends so that the frame becomes, in effect, an integral unit of standard dimensions that can be stocked in dierent sizes by suppliers of building material and yet'that'can be adapted to various building constructions.

Th head, sill and jambs are, also, each provided with adjustable anchors for secureinent of the window frame to the window opening.

Each of the sashes is provided with an extending ilange which engages a wire insert 9| formed preferably of self-lubricating metal, such as disclosed in United States Patent 2,250,723, isued to Edmund Peremi and Louis Toth on July 29, 1941, and which insert 9i is carried kby the parting strip of the jamb 25.

As hereinbefore noted, the window construction includes spring-balancers which cooperate with spring equalizers to permit the sashes'easily to be moved and yet positively to be maintained in adjusted positions. Thus, as shown in Figures 3 3 and 4, jamb channel l0 has disposed therein a cylinder 92 which is attached to the .lamb by suitable means, such, for instance, as follows: A screw 93 extends through a bushed opening in the cylinder 92 and is threaded into the wall of the jamb adjacent the upper end of the latter. The upper end S4 of a coll spring 95 is attached to the bushing 96. This spring extends downwardly, freely, through the cylinder '92 and is, at its lower end, attached at 91 to the hook 98 on the lower sash. This hook 08 is on the end of a strip 99 that is adjustably secured to the bottom rail 1| of the lower sash 2| by means of a screw and slot arrangement |00, which screw is reached through an opening in the weather stripping 80.

It will, of course, be understood that the opposite side of the sash 2| is provided with a similar balance spring arrangement,

Referring, now, to Figure 2, it will be seen that the upper sash is also provided, at each side, with a similar spring balancer. As illustrated in Figure 2, the upper end of this spring ||1, and its tubular housing |02, are secured to the adjacent jamb adjacent the upper end of the latter in a manner similar to that described in connection with Figure 4. The lower end of each of these springs |0| is attached to the lower or meeting rail of the upper sash in the following manner: A plate |03 is secured to the lower surface of the meeting rail of the upper sash by means such as a screw |04. An extension |05 terminates in a hook |06 to which the coil spring |0| is attached. Thus both the upper and lower sashes are provided with spring window balancers.

The relation between the tension of the sash balancing springs and the Weight of the sashes is such, preferably, that the: sashes will be supported substantially midway between their open.

in their closed positions and in various other open positions, we have provided sash balancer equalizers at opposite sides of the upper rail vof the lower sash and at opposite sides of the lower rail of the upper sash.

Refering to Figures 5 and '1, which illustrate an equalizer on the upper or meeting rail of the lower sash, the equalizer includes a plate |01 which is secured to the upper rail of the lower sash by means of a pivot, such as a screw |08. A portion of the plate |01 is bent upwardly as at |09 and has permanently attached thereto, by suitable means such as a rivet I|0, a resilient bearing member that extends into the adjacent channel of the window frame and is adapted to contact with the adjacent wall of the frame as, for instance, the inner wall of the portion 89 disclosed in Figure 7'. At the point of contact the bearing member is provided with a selflubrieating metal cover ||2. In order that the pressure exerted by this cover ||2 on the adjaprovided the plate |01 with a downwardly extending lip ||3 (see Figures 5 and 7) which projects through an opening III in the top of the meeting rail of the lower sash. An adjusting screw ||5 passes freely through the vertical face of the meeting rail of the lower sash and is in screw-threaded engagement with the lip |l3. Thus, by means of this screw H5, the position of the bearing member and the force exerted by its cover ||2 against the frame may be varied to increase or decrease that force and with the assistance of screw |08 will maintain the equalizer in its adjusted position. In this way the tension of the spring balancers of the lower sash may be equalized with the result that the sash may be raised and lowered with ease and yet will be maintained in its adjusted positions by means of the spring equalizers.

The lower or meeting rail oi the upper .sash is provided with similar equalizers, as illustrated in Figure 8, the principal difference between the two forms of equalizers being that the bearing member ||6 on each' upper sash equalizer and the cover I1 are carried by the extension |05 of the plate |03 which terminates inthe spring engaging hook |06. It might be here noted that the edge portion ||8 (see Figure 8) of the covers' ||2 and ||1 engage the adjacent portion of the frame and assist in correctly positioning the sashes within the frame against sidewise movement.

While we have illustrated and described the particular form of our invention it is to be understood that various changes may be made within the scope of the claims, and we, therefore, do not wish to be limited to the illustrated form except insofar as limitation is made necessary by the claims.
